Nextcloud Server before 9.0.55 and 10.0.2 suffers from a permission increase on re-sharing via OCS API issue. A permission related issue within the OCS sharing API allowed an authenticated adversary to reshare shared files with an increasing permission set. This may allow an attacker to edit files in a share despite having only a 'read' permission set. Note that this only affects folders and files that the adversary has at least read-only permissions for. Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 sufre un aumento de permiso al volver a compartir a través del problema de la API de OCS compartiendo API permitió a un adversario autenticado compartir archivos compartidos con un conjunto de permisos creciente. • https://hackerone.com/reports/169680 https://nextcloud.com/security/advisory/?id=nc-sa-2017-001 • CWE-275: Permission Issues CWE-732: Incorrect Permission Assignment for Critical Resource •

Nextcloud Server before 9.0.55 and 10.0.2 suffers from a bypass in the quota limitation. Due to not properly sanitizing values provided by the `OC-Total-Length` HTTP header an authenticated adversary may be able to exceed their configured user quota. Thus using more space than allowed by the administrator. Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 Sufre una evasión en la limitación de cuota. Debido a que no se desinfectan correctamente los valores proporcionados por la cabecera "OC-Total-Length" HTTP, un adversario autenticado puede superar su cuota de usuario configurada. • https://hackerone.com/reports/173622 https://nextcloud.com/security/advisory/?id=nc-sa-2017-005 • CWE-20: Improper Input Validation CWE-807: Reliance on Untrusted Inputs in a Security Decision •

Nextcloud Server before 9.0.55 and 10.0.2 suffers from a error message disclosing existence of file in write-only share. Due to an error in the application logic an adversary with access to a write-only share may enumerate the names of existing files and subfolders by comparing the exception messages. Nextcloud Server en versiones anteriores a 9.0.55 y 10.0.2 sufre de un mensaje de error que revela la existencia de archivo en el recurso de sólo escritura.

Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Reflected XSS in the Gallery application. The gallery app was not properly sanitizing exception messages from the Nextcloud/ownCloud server. Due to an endpoint where an attacker could influence the error message, this led to a reflected Cross-Site-Scripting vulnerability. Nextcloud Server en versiones anteriores a 10.0.1 y ownCloud Server en versiones anteriores a 9.0.6 y 9.1.2 sufren de Reflexed XSS en la aplicación Galería. La aplicación de la galería no estaba correctamente desinfectando los mensajes de excepción del servidor Nextcloud/ownCloud. • https://github.com/nextcloud/gallery/commit/f9ef505c1d60c9041e251682e0f6b3daad952d58 https://github.com/owncloud/gallery/commit/b3b3772fb9bec61ba10d357bef42b676fa474eee https://github.com/owncloud/gallery/commit/dc4887f1afcc0cf304f4a0694075c9364298ad8a https://hackerone.com/reports/165686 https://nextcloud.com/security/advisory/?id=nc-sa-2016-009 https://owncloud.org/security/advisory/?id=oc-sa-2016-019 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Nextcloud Server before 10.0.1 & ownCloud Server before 9.0.6 and 9.1.2 suffer from Stored XSS in CardDAV image export. The CardDAV image export functionality as implemented in Nextcloud/ownCloud allows the download of images stored within a vCard. Due to not performing any kind of verification on the image content this is prone to a stored Cross-Site Scripting attack. Nextcloud Server en versiones anteriores a 10.0.1 y ownCloud Server en versiones anteriores a 9.0.6 y 9.1.2 sufren de XSS almacenado en la exportación de imágenes CardDAV.
